load line types from lisp

[Angelo2449]

hello to all and good year wishes,
I would like to load from lisp of line types, I tried something but it does not work.
At present, with a small program in lisp, I create the layers that I need:

        (command "_layer" "_new" "rosso" "_color" "_red" "rosso" "")
        (command "_layer" "_new" "blu" "_color" "_blue" "blu" "")
        (command "_layer" "_new" "giallo" "_color" "_yellow" "giallo" "")
       ................
       ................

continuing, as mentioned, I would like to load line types like the "hidden", "hidden2", etc.
How can I proceed?
Thank you.

(command "_-linetype" "_l" "dashed" "acad.lin"")
acad.lin can also be acadious.lin

if they are already present, you are required to overwrite the existing line type; a quick way to avoid the request is to set the expert variable to 3 and after the command restore it.
